Slade Smiley is engaged to his longtime girlfriend and Real Housewives of Orange County costar, Gretchen Rossi, 34, after she recently proposed, PEOPLE has confirmed.

The popping of the question will be televised on Bravo's hit show.

"They're really happy about getting married," a source tells PEOPLE of the pair. "Gretchen always does everything out of the box, so no one is too surprised she was the one who proposed. She really wants kids with Slade, so that was a big motivator."

During the taping earlier this month, Andy Cohen was in the middle of asking Tamra Barney a question about her fiancé, Eddie Judge, and costar Vicki Gunvalson's boyfriend, Brooks Ayers, when the bird grazed by his head, drawing shrieks from the Housewives and prompting a flustered Cohen and some of the women to leap out of their chairs.

"Oh my God," Cohen said, shaking himself off after he had collected himself.

Bravo's summer programing slate is heating up, and the network has recruited a fleet of its "Bravolebrities" – more than 30 in total – for a fun, fast-paced new promo, and PEOPLE.com has a first look. (The commercial will make its TV debut during Wednesday's Watch What Happens Live.)

The Olympics-themed clip finds various Housewives – NeNe Leakes, Kyle Richards and Ramona Singer – facing off for race ... in heels! And with drinks in hand.

"We're trying to bury the hatchet," Gretchen tells her boyfriend Slade, who's totally against any form of reconciliation between the two women, whose hateful feud has fueled the series' recent seasons. "I just want to try and get all the negativity out of my life."

"Things with Gretchen have gotten so bad that it's basically me talking about her, her talking about me and just investing this time to dig up crap on each other's lives and for what?" Tamra explains, as the pair head out to make peace over mojitos, shrimp cocktail and meatballs.

The Real Housewives of Orange County, Bravo's original series in the franchise, returns Feb. 7, and it will feature stay-at-home mom Heather Dubrow, a former actress who is married to a prominent Newport Beach plastic surgeon. (Watch the video below.)

Armstrong, along with Atlanta's Kandi Burruss and Orange County's Gretchen Rossi, will be part of a team of Housewives to host Ciroc Vodka-sponsored New Year's Eve parties in Los Angeles, Chicago, Houston, New York City and Miami this year. Commercials for the events, which will be open to lucky contest winners, will air on Bravo.

"Taylor was in good spirits, talking to a few people about the new things happening in her life," the source says.
